The Fokker F27 Friendship is a turboprop airliner designed and built by the Dutch aircraft manufacturer Fokker.

[edit] History

Design of the Fokker F27 started in the 1950s as a replacement to the successful DC-3 airliner. The manufacturer evaluated a number of different configurations before finally deciding on a high wing twin Rolls-Royce Dart engined layout with a pressurised cabin for 28 passengers.

The first prototype, registered PH-NIV, first flew on 24 November 1955. The second prototype and initial production machines were 3 ft (0.9 m) longer, addressing the first aircraft's slightly tail-heavy handling and also providing space for more passengers. These aircraft also used the more powerful Dart Mk 528 engine.

In 1956 Fokker signed a licensing deal with the US aircraft manufacturer Fairchild for the latter to construct the F27 in the USA. The first U.S.-built aircraft flew on 12 April 1958. Fairchild also independently developed a stretched version, called the FH-227.

At the end of the Fokker F27s production,in 1987, 793 units had been built (including 207 in the USA by Fairchild), which makes it the most successful turboprop airliner of all time.

Many aircraft have been modified from passenger service to cargo or express-package freighter roles.

In the early 1980s, Fokker developed a successor to the Friendship, the Fokker 50. Although based on the F27-500 airframe, the Fokker 50 is virtually a new aircraft with Pratt & Whitney Canada engines and modern systems. Its general performance and passenger comfort are improved over the F27.

[edit] Variants

The first production model of the Fokker F27, the F27-100, which seated 44 passengers, was initially delivered to Aer Lingus in September 1958.
